<p>In a process and apparatus for storing and retrieving data so as to facilitate performing a price look-up function, a scanner (18) and a retail terminal (20) at a checkout counter (12) are used in conjunction with a U.P.C. number on an article to be sold. A EPROM (36) at the scanner (18) is used to store a compressed article description which is stored by U.P.C. number. The EPROM address for a "matched" U.P.C. number is used to obtain the corresponding price data in a RAM (30) also located at the scanner, thereby assisting in reducing the time required to effect a PLU function.</p> |
